13 discussions on ElectronDepot about the Tektronix SD-24: what owners asked, what went wrong, and what fixed it.
I was flipping through AoE III looking for anything on VCAs. (Doing a VCA whose noise doesn't tank at low gain is hard--I'll start another thread on that.) I noticed the "designs by the masters" sections, which are fun. My candidates...
Folks, After John Larkin sent me SMS7621 Schottky RF diodes I played around with them in the lab. While they perform nicely at room temperature everything goes to pots at a slightly elevated temperature. At ballpark 50C the leakage current...
I ordered two scopes from eBay, a couple of weeks apart, and they botharrived on the same day.#1: Tektronix 11801C 50 GHz sampling scope with SD-24 and SD-26plugins. I rely on my 11802 very heavily, so it makes sense to have aspare, and...
I bet Agilent wants a pretty penny for their new 32GHz real-time scopes: And to think that it was only ~20 years ago that a Tek 11802 with the SD-24 (24GHz) sampling head -- that samples at all of 100kHz -- was the hotest ticket... now...
Hi, Joerg:- What would be a expected capacitance for a working 8MHz doppler vascular ultrasound transducer? I measure about 250pF including cable capacitance, which could be just the ~6' of cable. --sp
Although I have done this many times myself, I thought this guy did very well in this demo. Years ago I had coax going up to the roof and it was in the walls to make things look pretty on the out side.. I had a DC short and I wasn't...
